ASTM A252 Grade 3 is specified for structural piling. Use the contracted edition, applicable test specimen and steel heat to finalize acceptance and certification.
| Property | ASTM A252 Grade 3 reference |
|---|---|
| Minimum yield strength | 45 ksi / 310 MPa |
| Minimum tensile strength | 66 ksi / 455 MPa |
| Elongation | A basic 20% minimum in a 2 in. (50 mm) specimen is shown for nominal walls at least 7.9 mm in earlier published editions; adjust for thinner walls and verify the 2026 edition. |
| Phosphorus (P) | Maximum 0.050% in established published A252 requirements |
| Other chemistry | Request heat chemistry and project-specific C, Mn, S or weldability limits when relevant; the listed A252 chemical limit alone does not define all heat analysis values. |
The 310 MPa and 455 MPa minimum values are documented Grade 3 references; final contractual compliance is measured against the purchased standard and test certificates.
The three grades have different published strength minima. Selecting Grade 3 raises the specified steel strength, while pile load capacity also depends on section geometry, installation conditions and geotechnical design.
| Pipe pile grade | Min. yield (reference) | Min. tensile (reference) | Project selection |
|---|---|---|---|
| ASTM A252 Grade 1 | 205 MPa / 30 ksi | 345 MPa / 50 ksi | Lower strength class for project-specific design |
| ASTM A252 Grade 2 | 240 MPa / 35 ksi | 415 MPa / 60 ksi | Intermediate structural piling class |
| ASTM A252 Grade 3 | 310 MPa / 45 ksi | 455 MPa / 66 ksi | Higher minimum strength for specified pile sections |
Strength values reference published Grade 1–3 requirements; use the engineer-approved pile section, applicable edition and certificate for final selection. Changes between grades require design review.
Send the pile schedule with grade, OD, WT and lengths so each line can be quoted accurately.
A252 covers both seamless and welded pile products. Route selection depends on required diameter, wall thickness, length, mill qualification and the project specification.
Steel strip or plate is formed into a cylinder with a longitudinal joint. Confirm actual seam process, range of OD and WT, seam quality requirements and project-specific inspection.
Helical welded construction is commonly considered for larger piling diameters. Record the helical-butt or other approved seam description and confirm pipe-roundness, length, seam testing and end preparation.
Seamless piling may be considered where the proposed diameter and wall fall within the mill production range. Supply and price depend on the exact section and required fabrication.
Pipe piling is normally purchased by actual outside diameter and nominal wall rather than standard line-pipe schedules. A project may also specify corrosion allowance, installation straightness and weld preparation.
| Common OD reference | Example OD | Ordering note |
|---|---|---|
| 8⅝ in. | 219.1 mm | Confirm actual wall and available lengths |
| 10¾ in. | 273.1 mm | Check section and pile driving arrangement |
| 12¾ in. | 323.9 mm | Suitable for project-specific wall choice |
| 16 in. | 406.4 mm | Confirm welded route and lifting plan |
| 20 in. | 508.0 mm | Wall thickness and weld seam by design |
| 24 in. | 609.6 mm | Large diameter pile; project mill availability |
| 36 in. | 914.4 mm | Verify production route, WT and handling |
Dimensions above are quotation reference points, not a universal inventory or standard-stock list. Specify your actual OD and WT.
Published A252 mill literature describes OD, wall and unit-weight tolerances. Confirm the allowable tolerances in the contracted 2026 specification and project documents.
Installation method affects cutting, end treatment and fabrication. Provide your pile details, construction drawings and the responsible engineer’s specifications with the enquiry.
Pipe is driven with an open toe where the soil and installation plan allow. A cutting shoe or toe reinforcement can be specified separately with fabrication drawings.
Closed-end piling uses a project-designed plate, cap or shoe at the toe. Confirm end closure geometry, attachment welds and inspection requirements.
For long piles, define splice type, welding procedure, alignment tolerance, joint testing and the number of field sections in the foundation schedule.
A252 Grade 3 may be specified where the steel pipe forms the permanent structural pile or a casing for cast-in-place concrete, subject to the approved foundation design.
Deep foundations supporting bridge piers, abutments and associated civil infrastructure.
Pipe piles for wharves, jetties and marine infrastructure with project-specific corrosion protection.
Structural piling beneath heavy equipment, large buildings and industrial support structures.
Foundation piles for elevated roadways, rail facilities and retaining structures.

Quality control →Align pile lengths, loading, handling protection, shipping terms and destination documentation with the purchase order.
For structural pipe piles, the test and traceability package should match the selected ASTM edition, pipe manufacturing process, foundation BOQ and required welding inspections.
Coordinate any special work from the design drawings. Pipe length, butt joint details and toe configuration should be set before fabrication starts.
Attach end-detail drawings with your BOQ so the quotation can include required material, welding, checks and handling provisions.
Pipe pile supply depends on diameter, thickness, selected welding route, project lengths, inspection scope and destination. A detailed BOQ helps verify the optimal mill lot and transport plan.
Group pile materials by outside diameter, nominal wall, cut length and quantity. State the load-bearing pipe steel requirements, end closures, site welding or splice details, testing package and required shipment sequence.
Agree safe lift points, support blocks, load securing and piece identification for each pipe size. Long lengths and heavy wall sections affect transport arrangements.
For oversize pipe piles, confirm the loading location, port capability and available transport method before finalizing the shipping term.
A252 pipe piling supports a structural foundation design, which also includes soil conditions, driving or drilling methods, corrosion protection and field connections.
Confirm axial and lateral resistance, local buckling, pile section loss allowances and connection capacity with the project designer.
Record open or closed toe, required drivability, anticipated refusal criteria, lifting points and planned splices.
Identify mill tests, weld inspections, site receipt checks and any independent inspection before ordering.
